Amazon announced Tuesday that it will join with J.P. Morgan Chase and Berkshire Hathaway to wade into the jungle of U.S. health care, and the news slashed billions in stock-market value from health-care companies in mere hours. American health care could benefit from creative destruction, though this would be Amazon’s toughest fixer upper to date.

The announcement offered no details—nothing on if the companies will set up provider networks or walk-in clinics or what. But an early red flag: The press release says the group will form an “independent company that is free from profit-making incentives and constraints.”

The problem with U.S. health care is not an incentive for profit, which has driven innovation and cures for diseases like hepatitis C. The fundamental problem is that the cost of a service is disconnected from underlying value. Patients don’t know the price of services and consume health care as if it’s free since government or employers are the third-party payers for most Americans.
